You will not need libfaac if you're also including libfdk-aac:

Do you need --enable-librtmp? The native rtmp protocol support should
probably suffice.

People actually use AMR and speex these days?

--enable-x11grab requires some dependencies. In your case these are
probably fulfilled by the packages: libx11-dev libxext-dev
libxfixes-dev. If you do not need x11grab (to record the screen) then
remove --enable-x11grab.

Generally the inclusion of the tail (or at least the last ~50 lines) of
config.log is recommended.

If you need help compiling for Debian see:
